Capture, unless it's changed since ICBT2, gets pretty insane You aren't so much capturing a single skill, as much as you are taking a snapshot of a small area, and copying everything in that area, to be pasted somewhere else later. You can copy as many ground-targeted Magic Circles at once as you can possibly cram into the search-radius of Capture. You can capture and reproduce over 20 Heal Tiles, Safety Zone, and Cure from a single cast of Capture, simply because all of those abilities were placed on top of each other for Capture to grab. It also retains the skill level and attributes of the skills copied, it's amazingly powerful.
Also sorry but that rogue rework thread is terrible, Have you played rogue? Backstab moved to c3? Larchrymator buffed? No change to burrow (it's already scheduled for changes) and wtf are you suggesting to do to sneak hit, that suggestion makes it look like a mangled backstab.
